Abstract
Abstract The invention discloses a steam and power spray iron wherein generated steam pressure is used to power the spray assembly. The invention is directed to an improvement in the spray assembly that provides a continuous steam tube directly connected at one end to the spray assembly and extending down into close proximity to the steam generator at the other end whereby, as soon as steam is generated, it is ducted directly and immediately to the spray assembly to provide steam power therefor without significant heat losses.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
91 words
In a steam and spray iron having a closed water reservoir and a single steam generator connected to receive water from said reservoir through a metering valve and direct steam to both the ironing surface and to the reservoir to pressurize said reservoir, the improvement in a continuous steam-powered spray assembly comprising, a spray nozzle on said iron having a water tube connecting with said reservoir and terminating in a spray aperture in said assembly, and a steam tube directly connecting the spray aperture and steam generator through said water reservoir.
